Echo, Posterize Time and the other Time effects read the layer at other times with none of
its effects. After Effects renders them with the effects before them: SceneYard "Task
Preparation UI" applies Echo after CC Particle Systems II on black solids, and AE shows the
echoed fireworks over a white page where we echoed the black solids and blacked it out
(Posterize Time after Turbulent Displace, the usual stop-motion setup, depends on the same).
The host already bounds the count to the effects before the one rendering.
Mean abs error vs AE: Task Preparation UI 0.1855 -> 0.0071, Lightbulb Idea 0.0126 -> 0.0102;
the 15 other corpus projects with a Time effect after another effect are pixel-identical.

Every pin move re-rendered the Puppet's input (source, masks and the
effects before it) at full size on the UI thread and deep-copied it
for the mesh overlay: the cache key of a layer's input hashed all of
its effects, so moving a pin of the Puppet changed the key of its own
input. The input key now covers only the effects that run before the
Puppet, and the overlay shares the cached buffer.
Test: input_keys_ignore_later_effects.

EffectHost gains self_at (the layer's source + masks + first N effects at
another layer time) and layer_at (another layer at another comp time);
EffectEnv carries the effect's stack index. The renderer serves these via
Renderer::layer_input, cached in the layer cache under input keys (footage
included, keyed by source time) with a depth guard against recursion.
Time effects are TIME_DEPENDENT so processed-layer keys fold in layer
time; layers with time effects and expressions are not cached.
Also registers the Effect > Audio specs (DSP in effects::audio_fx; the
mixdown integration follows in M11.2). Audio effects are skipped by the
video effect pass.
